Running Multiple Instances of Your App - Misleading description

Under the section [Scaling a Deployment](https://kubernetes.io/docs/tutorials/kubernetes-basics/scale/scale-intro/#scaling-a-deployment), there is an explanation of the output of `kubectl get deployments`. The point READY shows the ratio of CURRENT/DESIRED replicas is misleading and should be READY/DESIRED, since CURRENT has its own meaning that's different from READY.

Open the linked Scaling a Deployment section and review the explanation of kubectl get deployments output. Update the READY description to use READY/DESIRED while preserving the distinction that CURRENT has its own meaning; done when the documentation matches the command's column meanings.
